These two unique assemblies are making their hobby debut within a three-day Extended Bidding auction, sharing the podium with the usual assortment of rare and important trading cards, autographs, game used gear and general ephemera for which Heritage is known.

"In the two years since his passing at age 91, LeRoy Neiman has seen a significant surge in his already red-hot collecting market," said Chris Ivy, Director of Sports Auctions at Heritage, "with Heritage posting no fewer than four six-figure sales during the period. We expect interest in The Charlie McCabe Collection to be very high."

The McCabe Collection of Neiman Baseball Art was assembled over the course of a four decade friendship between McCabe, one of the most influential New York bank marketing executives ever, and the legendary artist. It features more than 100 original artworks celebrating many of the greatest names in the sporting world and beyond on the unlikely spherical media of baseballs. Highlights, among the many, include a 1992 Joe DiMaggio signed baseball with Marilyn Monroe artwork and a 1995 Babe Ruth original baseball artwork, issued to commemorate the Babe's 100th birthday.

"While Ernie Schworck's name may not be as famous as Neiman's," said Ivy, "his photography is instantly recognizable to anybody who was reading the sports pages in the 1960s. With his proximity to great players and great moments, Ernie had the chance to acquire some very important game-used baseballs and to, unknowingly perhaps, build a world-class collection. These momentous balls were kept in his desk drawer for years."

Heritage is also offering a significant 1965 Sandy Koufax game worn Los Angeles Dodgers jersey from the hurler's Cy Young and World Championship season. The jersey is considered the finest known Koufax gamer in the hobby and bears top uniform authentication service MEARS' highest assessment of A10.

The auction is currently open for bidding and it is divided into three separate sessions, with each session closing via Extended Bidding format. Session 1 consists of Trading cards, which will close at 10pm Central time on Thursday, May 15. Session 2, which begins with the aforementioned LeRoy Neiman Collection and continues on to include the balance of the event's high-end sports memorabilia offerings, will close the evening of Friday, May 16. The Final Session, will close on Saturday, May 17, and is comprised of more modestly-priced collectibles of all types, from trading cards to autographs and general ephemera.
